Busch
Abraham Albert Busch was a prominent watchmaker in the Hanseatic city of Hamburg during the late 17^th and early 18^th centuries. In 1721 his younger brother, Friedrich Wilhelm Busch, followed in his footsteps and while Abraham Albert was the more established figure, he and his brother are both recognised in horological history for their contributions to North German watchmaking. Their surviving pieces are considered rare and frequently appear in high end horological auctions.
